In the summer of 1910, Stravinsky moved with his family to Clarens, on the shores of Lake Geneva. He then had the idea to compose an orchestral piece in which the piano would play a predominant role. “In composing the music, I had in mind a distinct picture of a puppet, suddenly endowed with life, exasperating the patience of the orchestra with diabolical cascades of arpeggios. The orchestra, in turn, retaliates with menacing trumpet blasts. The outcome is a terrific noise which reaches its climax and ends in the sorrowful and querulous collapse of the poor puppet,” the composer explained in his Autobiography. The impresario Diaghilev was very enthusiastic about the project and immediately persuading Stravinsky "to develop the theme of the puppet's sufferings and make it into a whole ballet." The Ballets Russes premiered Petrushka on 13 June 1911 in Paris under Pierre Monteux. Vaslav Nijinsky – for whom Stravinsky had much admiration – danced the title role in Michel Fokine's choreography. The press was somewhat divided after the dress rehearsal, but the public gave the first performance an enthusiastic ovation. A year after completing The Firebird, Stravinsky demonstrated with Petrushka that he was near to achieving a musical language resolutely turned towards the future in terms of harmony, instrumentation and rhythm. "Petrushka is the first of Stravinsky's works of importance where the composer is completely himself," said conductor Ernest Ansermet. In 1947, Stravinsky reorchestrated Petrushka, reducing the number of instruments to make the piece more suitable for concert performances.
